Not working on Mac OS X 10.7.5

[duksis]

Tried to run the test suite and got the following:

$ ./tests.sh 
(standard_in) 1: illegal character: N
(standard_in) 1: illegal character: N
all 8 demo tests passed in s.
(standard_in) 1: illegal character: N
(standard_in) 1: illegal character: N
test #8 "_clean INVARIANT=;
assert_end | egrep 'all 0 tests passed in [0-9].[0-9]{3}s'" failed:
    program terminated with code 1 instead of 0
1 of 9 output tests failed in s.
(standard_in) 1: illegal character: N
(standard_in) 1: illegal character: N
all 7 regression tests passed in s.
duksihug@WL038424 ~/code/assert.sh (master)
$ echo $BASH_VERSION
3.2.48(1)-release

looks like one of the causes is that the default date command shipped with mac os does not have a %N (nanosecond) formatting option

P.S.
Great project - would love to use it.

Thanks for the report! date indeed seems to be the culprit: It leaves straw %N tokens around when it cannot understand them. Subsequently, bc trips up when trying to calculate 123.%N - 120.%N.
It should be fixed in b7a4213 — can you confirm?

[duksis]

Not sure if this was intended that way but b7a4213 returns the github 404 page

Could you try again? It works for me now.

[duksis]

the link works now, but the test suite don't

$ ./tests.sh 
(standard_in) 1: illegal character: N
(standard_in) 1: illegal character: N
all 9 demo tests passed in s.
(standard_in) 1: illegal character: N
(standard_in) 1: illegal character: N
test #8 "_clean INVARIANT=;
assert_end | egrep 'all 0 tests passed in [0-9].[0-9]{3}s'" failed:
    program terminated with code 1 instead of 0
1 of 13 output tests failed in s.
(standard_in) 1: illegal character: N
(standard_in) 1: illegal character: N
all 7 regression tests passed in s.

Added code that works for me:

• non existing formatting option adds a ".N" to the string at-least for me.
• and one of the tests expects nanoseconds but they are not there
